i have a 2004 gmc sierra 5.3 ext cab 4x4. stock 3:73 gears on 16in rims 32.5 in tires... mods so far are CAI,Lt's with off road Y, Nelsons 91 tune, Ported TB, Tbss injectors, TR 220 cam on 114 lsa, vette servos. I was trying to get a guess at what my 1/4 time might be....

Tomorrow night ill be picking up some 706 heads, ported and polished milled .030 with a ported intake to match. I was wondering what you all think that would bump me too. hopefully in the next month or 2 ill have a cir-d 3000-3200 stall installed as well im shooting for low low 13's?
